SMALL ARM EXPLOSIVE SHELL Filed Sept. 20, 1926 9 aw z uNiT EDi stares p 7 This invention aims to provide a novel form ofbullet, adapted to be used, ordi- 1 narily, in small arms, and so constructed that i when it strikes an obstacle, it will explode. It is within the province of the disclosure i utility'ot devices of that type to which the N invention appertains. V

WVith' the above and other objects in view which will appear as the description proceeds, the invention resides in the co1nbination and arrangement of parts and in the fidetails' of construction hereinafter described 3 and claimed, it being understood that changes'in the precise embodiment'o'f the invention herein disclosed, may be made withinthe scope of what is claimed, without 1 departing troin-thespirit of the invention. In the drawings Y Figure 1 shcwsin elevation, a device coni l t I "Figure 2 is a longitudinal section;

of Figure, 2; Figure 4 is a cross section on ofFigure 2. The device forming the subject matter of this application comprises a casing 1 of tubular form, and made of steel. Vi ithin the casing 1 is located the body 2 which is made of softer metal than the casing l, the constituent metal or" the body 2 being soft enough so that it will mushroom when the I bluntly pointed end 3 of the body strikes the line H Q casing 1 and is supplied in its rear end with preferably, but not necessarily, being of conical outline. In the body 2 is embedded a -,firing pin 5, made of'hard metal, the rear 'chamber 4 and carrying an enlarged head 6, which maybe in the form of a ball, the head 5 to? improve generally and to enhance the structed inaccordance with the invention] an obstacle. .The body 2 is secured in the 1 a chamber 4 for the explosive, this chamber,

ward, and the head 6 of the firing pin strikes the projection 7 the said projection being in the form of a cap which will set cit the explosive 11in the chamber 4, the bullet then bursting-with great effect.

' The bullet hereinbetore'described is assem bled with a cartridge (not shown) containing a propelling charge. v

What is claimed is A bullet including a tubular casing, a

v butt piece threaded into the rear end of the Y Figure 3 is a cross section on the line 33 casing, the butt piece beingprovided with means whereby it may befrotated, the butt piece being provided on its inner surface with a projection, abody Within the casing and inengagement with the butt piece, the body having a chamber in its rear end, for

the reception of an explosive, to hold the" explosive about the projection, and a firing pin mounted in the body and, extended backwardly into the chamber, the firing pin being provided with an enlarged head located in the chamber and in alin'en ent with the projection on the butt piece, the constitue ent material of the body being soft enough so that it will mushroom and drive the firing pin backwardly, thereby carrying the head'of the firing pin into engagement with the projection on the butt piece. i
